Saks also raised its target for cost cuts, as it expects sales will continue to decline for the rest of the year.
Saks said it now expects a reduction of about $60 million in selling, general and administrative costs in 2009, from its prior expectation of $20 million to $30 million.
It also said capital expenditures would be about $55 million, down from the $60 million it expected earlier.

Saks' net loss was $5.1 million, or 4 cents per share, in the fiscal first quarter that ended May 2, compared with a profit of $17.3 million or 12 cents per share, a year earlier.
Excluding some charges, its loss of 3 cents per share was much smaller than the loss of 26 cents per share expected on average, according to Reuters Estimates.
Sales fell 26.9 percent to $621.3 million, as sales at stores open at least a year dropped 27.6 percent.
For the full year, Saks still forecast same-store sales to decline in the low double digit percentage range. It is also targeting a 20 percent decrease in inventory for 2009.
Earlier this year, Saks dismissed rumors that it could seek bankruptcy protection, and said it was still committed to luxury, would intensify its focus on some brands and expects to have ample liquidity this year.
Saks shares were up 17.1 percent at $4.78 in premarket trading from Monday's closing price of $4.08.
